This essay examines how medical rhetorics helped justify the recent torrent of anti-trans legislation. Beginning with the “legitimacy wars” between psychiatry and psychology, I trace how competing disciplines established their own expertise by denying trans patients’ agency and self-knowledge. After identifying the “trans trickster” trope that emerges from these rhetorics, I trace how the trans trickster haunts arguments used to ban gender-affirming health care and sports participation for trans youth. I draw from sociologist Ian Hacking’s “looping effects” to explain how medical logics affect public perception and how those understandings loop back into medical research. The binary, linear models of gender transition established by trans medicine helped justify cisnormative policies around transgender identity, which in turn restricted further scientific inquiry such that more imaginative gender formations remain illegible. To conclude, I argue that medical paradigms work in relation with trans imagination would expand scientific explorations of human diversity, and that those understandings too could loop through public policy and perception.

Our article uses case studies of two civilian emergency response mHealth apps—PulsePoint and OD Help—to theorize the ways the mobile mapping functionality embedded in these tools, which is integrated with the Google Maps platform, enables yet also constrains users’ agential practices. Using an interface rhetoric approach, we unpack assumptions related to the embodied contexts of use facilitated by this functionality within the unique scenario of civilian emergency response. We argue that interactions between and among humans and these apps’ mapping interfaces involve complex, negotiated, contextually situated enactments, which align with a posthumanist perspective toward agency. At the same time, these interactions may also inadvertently amplify the precarity of vulnerable groups. Better understanding the ways that mobile mapping technologies shape agential enactments, particularly in ways that affect precarious and dispossessed populations, has important implications for the design of mHealth technologies—and the users who rely on them—moving forward.

When considering the material ecologies of the human body, we must consider the bodies within—at least five hundred known species of microbes. We propose the term gut rhetorics to highlight how our guts have become an environment to which we are exposed: a biologically active actant contributing to the physiology and psychology—the rhetorical capacities—of the human body. Gut rhetorics incorporate—bring into the body and, importantly, into the body of rhetoric—the hungry horde within human bodies. First, we trace one probiotic formulation across three scientific studies to show how bodies, affects, and microbes are being “calibrated” at the level of experiment. Second, we stress skilled probiotic experimentation and encourage scholars to play amid environments, give attention to embodiment, and pursue phenomenological inquiry (Gruber, 2018; Melonçon, 2018). Gut rhetorics consider bodies, affects, and microbiota as entangled metabolic intra-actions that affect how the world appears to the body and the body to the world.
